本文实例讲述了jsp中变量及方法的声明与使用。分享给大家供大家参考，具体如下：
<%@ page language="java" import="java.util.*" contentType="text/html;charset=GBK"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"> <title>JSP 中声明的使用</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> <!-- <link rel="stylesheet" type="text/css" href="styles.css"> --> </head> <body> <h1 align="center">演示声明的使用</h1> <%--声明变量--%> <%!long i = 1,j=1; %> <%!String name="陈宁"; %> <%!String name2="官林辉"; %> <%--声明方法--%> <%!public String sayHello(String who) { return "您好："+who; } %> <p align="center"> <% out.println(sayHello(name)); out.println("<br>"); out.println("您是第"+i+"个访问本网站的用户！"); i++; %> <% Date time = new Date(); out.write(time.toLocaleString()); %> </p> <p align="center"> <%=sayHello(name2)%> <br> 您是第<%= j%>个访问本网站的用户！ <%j++;%> </p> </body> </html>
希望本文所述对大家jsp程序设计有所帮助。
